31.. PROFIBUS Fieldbus Interface

19

The PROFIBUS-DP

Interface

3

Fig. 14 shows the communication between the automation unit (DP master) and the MOVITRAC

®

31.. frequency inverter via one process data word only. This configuration could be used, for exam-
ple, to control the inverter with control word 1 and status word 1 (see SEW documentation

Field-

bus Unit Profile User Manual).

Fig. 14: Control of the inverter via 1 process data word

3 .1.3

Configuring for 2 Process Data Words (2 PD)

Control of the MOVITRAC

®

31.. inverter using two process data words requires that the Cfg_Data

identifier byte is coded as shown in Fig. 15. This code must be sent to the inverter by the DP mas-
ter when PROFIBUS-DP is started so that the DP master and DP slave can exchange two process
data words.

Fig. 16 shows the communication between the automation unit (DP master) and the MOVITRAC

®

31.. frequency inverter via two process data words. The higher-level control system could use this
configuration, for example, to send the process output data

Control Word 1 and Speed Setpoint

and read in the process input data

Status Word 1 and Speed Actual Value (see SEW documentation

Fieldbus Unit Profile User Manual).
